This is the saddest but most important Christmas advert this year

Without doubt, this is the saddest Christmas advert you'll see this year.

Santa Forgot, from Alzheimer's Research UK, is narrated by actor and writer Stephen Fry and imagines a world where Santa is living with the effects of dementia and no longer visits children on Christmas Eve.

It focuses on a little girl named Freya, who is preparing for a magical Christmas. She gets told a story by her dad about why Santa no longer visits because he began to mix up presents, muddle names and seemed sad.

Soon, Freya set off on a journey because she believes something can be done, and enlists the help of the elves in the workshop to make Santa feel better.

Alzheimer's Research UK, who are fighting misconceptions about dementia with #SantaForgot, ends on the note: 'If Santa had a disease, research could find a way to fix it.'
